Problem with Logitech G13 and Keyboard... patch or power issue?

So 2 nights ago, I had 2 brief power brownouts at my house, which turned everything off. Since that point, The Logitech G13 Gamepad and Keyboard have been erratic, and they will often not respond to spammed macros (keypress to repeat). The keys function normally.

I don’t know if some Logitech software patch goofed up things when everything restarted, or if some minor wow patch did this, or if a power issue did it.

Any ideas?
